Abstract

The invention discloses a shoe with PU (polyurethane) borders and a non-slip rubber outsole and a method for preparing the shoe. The shoe and the method have the advantages that the difficult problemsof low non-slip coefficients and incapability of preventing slipping of all-PU shoe soles can be solved by the aid of the shoe and the method, and the wearing safety can be improved; rubber is high in density and excellent in tensile property and tear resistance, a shoe sole is high in stiffness, and the durability of the shoe which is a product can be improved; various performance measurement values of the hardness, the tensile strength, the elongation at break, the abrasion and the like are excellent in stability and reproducibility, and the usability of the rubber shoe sole for the shoe iseasy to guarantee; PU shoe edges are adhered with a shoe upper and the rubber sole instead of rubber, accordingly, the density of the shoe edges can be lowered, the integral weight of the shoe can belowered, and the shortcoming of heaviness of rubber shoes can be overcome; rubber shoe lightweight and non-slip safety can be unified, and the use function range of the shoe can be extended; fiber lint is used as a bridging layer between the rubber and PU, accordingly, separation openings due to polarity difference of the PU and the rubber can be eliminated, the high-elasticity non-slip rubber and light foam PU layers can be firmly adhered with one another, and the solid waste generation rate can be reduced.

Description

technical field [0001] The invention relates to a processing technology of rubber-soled PU shoes, in particular to a preparation method of PU edge-slip anti-slip rubber outsole shoes. Background technique [0002] In the development trend of rubber shoes, lightweight has always been one of the requirements of the wearer, and the non-slip outsole is the first goal of safety. Therefore, both light and non-slip are the core of the comprehensive requirements of shoes. [0003] The first big disadvantage is that the shoes with rubber as the outer sole and the skirt of the shoe are bulky. [0004] Using PU as the shoe material, lightweight is its highlight. And its shortcoming is that the antiskid performance of the outsole is poor, and wearing safety degree is low. At the same time, the safe storage period and service life of polyester PU shoes are relatively short. The overall performance of polyether PU shoe materials is relatively better than that of polyester PU. [0005...
